can someone give me an estimation on how much hp will this combo make?

Close to 500 easily, if not more perhaps, i need to know the .050 specs of the cam and LSA.


What kind of hood is on the camaro in your sig? Jongbloed?

thats somewhere between 475-510 hp at the flywheel,real similar to our 505 hp engine,not sure of the flow #'s of the heads.

good I don't want to exceed 500HP NA

Can I spray 150hp over this ? my rods are I beam GM performance and the crank is SCAT steel

is it a forged or cast steel crank?

If they are the gm "pink" rods, i would not spray nitrous on top of that. They max out in the 450-500 hp range. If you are going to spray it, get some h-beam rods, such as eagle esp's. As previously stated, do you have a forged steel crank and pistons?

With a cam that big, I would consider putting a victor jr, or super victor type intake on that motor. It has to peak well over 7000 in a 383. Its good to see that it is a solid cam. Is it a solid roller or a flat tappet?

Yep, 500 is easily possible, but as stated, you are really pushing those rods.

I'm going to guess 515 HP & 539 TQ, at least that is what my Dynomation program thinks. Those are some nice heads and will make plenty of power. Make sure to gasket match the intake your heads, Edlebrock made some tiny openings for their casting's. I wouldn't worry about the crankshaft, the rods will break way before the crank will. If you haven't ordered your cam yet, you will want to favor the exhaust side a bit more. Here are some figures for a cam that I have found to work quite well with those heads as cast:
Adv. Duration 288/296
@.050 Dur. 250/258
Lift w/1.6 rocker .600"/.600" (hot lash @.020"/.022") net lift .580"/.578"
LSA 111*
ICL 107*
This cam also makes good intake vaccum for your brakes as well.

are these rods good for 150hp nos over this stroker?

those rods would be fine,but you need to know what the crank and pistons are before you start spraying them
